The measurement of dynamic pressure distortion requires noticeable effort in instrumentation and data processing. Considerable reductions in cost can be achieved by simpler methods. Examples of which will be given. In addition, the relevance of dynamic distortion on intake/engine compatibility has been overestimated as will be demonstrated by the experience gained from Tornado where swirl emerged as the decisive compatibility parameter. Also, during the Airbus A300 APU intake development swirl turned out to be an important criterion. In conclusion, it is argued whether in many cases dynamic distortion measurements can be avoided in favour of swirl measurements in combination with simplified methods for dynamic distortion predictions based on steady state measurements and, in some methods, on statistical models.
